Definition from Google. noun:
the avoidance, often considered as taken to extremes, of forms of expression or action that are perceived to exclude, marginalize, or insult groups of people who are socially disadvantaged or discriminated against.
A simple example: If Laura, Kate and Sarah go out for lunch, they will call each other Laura, Kate and Sarah. If Mike, Dave and John go out, they will affectionately refer to each other as Fat Boy, Bubba and Wildman. Is this offensive to the men doing the nicknaming? Is it offensive to others who might hear them? Does it matter?
A more complex example: As reported in the media, in a memo to students sent out by West Virginia University (WVU), Title IX coordinator James Goins, Jr. declares that anyone who refuses to use a person’s preferred transgender pronouns is breaking federal law!
A political example: Robert Litan, a Democrat, was fired from his left leaning think tank after delivering testimony against an Elizabeth Warren-backed Labor Department plan to regulate financial advisers. Half of House Democrats and virtually all Republicans in Congress oppose the plan because of its costs. Instead of rebutting his argument, Ms. Warren decided to punish it, he was fired from his think tank.
One ridiculous example: Princeton University’s ‘Men’s Engagement Manager’, to rehabilitate men that are too masculine.
Obviously there are many more, even more dramatic, examples of political correctness gone wild in our culture today.
Political correctness can be best described as the opposite of or the enemy of truth.
